Abstract
The invention relates to a fixing device of a rugged liquid crystal display. The fixing device comprises a screw head and a screw tail, the screw head and the screw tail are integrally formed, the screw tail is inserted into a screw hole of the rugged liquid crystal display, an I-shaped groove is formed in an end face of the screw head, the screw tail comprises a front part and a rear part, the rear part is connected with one end of the front part and the screw head respectively, and an end face of the other end of the front part is of a plane structure and provided with an M6 thread. Compared with the prior art, the fixing device of the rugged liquid crystal display has the advantages of strong compression resistance and soundness and the like.
Description
Technical field
The present invention relates to a kind of fixing device, especially relate to a kind of fixing device for reinforced liquid crystal displays.
Background technique
At present, the screw of supplying on market belongs to standard piece, and its effect is only and bolt two solids that are connected, and can not bear certain pressure, and easily at equipment, uses, is given a shock in transportation process and come off.In the long-time bearing certain pressure of needs and keep the fixing of tight occasion, particularly liquid crystal display, plain screw can not be satisfied the demand.
Summary of the invention
Purpose of the present invention is exactly that a kind of pressure resistance, the fixing device for reinforced liquid crystal displays that soundness is strong are provided in order to overcome the defect that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of fixing device for reinforced liquid crystal displays, is characterized in that, comprises screw head and screw afterbody, and described screw head and screw afterbody are one-body molded, and described screw afterbody inserts in the screw hole of reinforced liquid crystal displays.
The end face of described screw head is provided with the in-line groove.
The width of described groove is 0.1～0.2 of screw head diameter.
Described screw afterbody comprises fore-end and rear end part, and described rear end part is connected with screw head with an end of fore-end respectively, and the end face of the other end of fore-end is plane structure, and is provided with the M6 screw thread.
The diameter of described fore-end is larger than the diameter of rear end part.
The two end part of described fore-end are equipped with the chamfering of 45 °.
The material of described screw head and screw afterbody is the round steel material.
Compared with prior art, the present invention has the following advantages:
1, the mode that utilize the change material, increases thick intermediate section is strengthened its fastness, has changed on the existing market by the mode of GB plain screw, has possessed pressure resistance simultaneously and has increased the function of fastness.
2, in use, after screw is fixing, the conical surface of original GB screw changes plane in the present invention, and material changes round steel into, the intermediate section overstriking.In the occasion of using at the long-time bearing certain pressure of needs and equipment, being given a shock in transportation process, special screw can loose or dislocation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after the present invention is contained in reinforced liquid crystal displays.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
